Dehydration-responsive alterations in the chloroplast proteome and cell metabolomic profile of rice reveals key stress adaptation responses

Abstract

Chloroplast is a semi-autonomous organelle in plants and other photosynthetic eukaryotes, playing a fundamental role of regulating photosynthesis. It is also responsible for sustaining essential biosynthetic reactions including synthesis of amino acids, fatty acids and terpenes. Photosynthesis, the conversion of light energy into chemical energy, serves as the sensor of environmental changes and augments different cellular functions to initiate adaptive responses. However, the molecular processes and regulatory mechanisms of dehydration tolerance adopted by chloroplast remain largely unknown. To gain a better understanding of dehydration response, a chloroplast proteome map of rice was devel..
